Obviously I am missing something here.
I am trying to create a widget type of app, so all i want the site owner to have to do is drop 1 line of code (for now no params) into their HTML. So for example below.

I have an HTML page with this in the body:
<script type="text/javascript" src="http://mydomain.com/dev/calendar/cal.php"></script>

in the cal.php I have
Code:
<?php 
$buf = <<<BUF
document.write("<script type=\"text/javascript\" src=\"http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js\"></script>");

$(document).ready(function(){
alert('aaa');
});
BUF;
echo $buf;
?>

if I monitor the headers, I can see the browser pull down the jquery library, no problem. but the .ready event never fires, and i think its because it has already happened. THe page is already done, THEN the jquery library is pulled down?

so without a .ready event available wtf do i do here to get my code to run. in this case just a simple alert box.

Set a timeout. I believe you're right, the ready event would have fired when the page was completely parsed and up, no? I don't believe that writing to the document would re-trigger that event.

bah its the stupid timing. I gotta do a timeout it seems.

though I think i will instead loop until i detect the jquery lib being available.

Curious how are you monitoring those headers?

when looping, how did you determine that the lib had become available?

You can ask JavaScript if a function exists. If not, it's not loaded yet.

This threw me off too.. Wink

window.foo tests the existence window.foo() actually calls
the function.



Code:
<html>
<script language="javascript" type="text/javascript">

function foo() {
return false;
}


if(window.foo()) {
  document.writeln('foo returned true <br />');
}
else {
  document.writeln('foo returned not true<br />');
}


if(window.foo) {
  document.writeln('foo exists <br />');
}
else {
  document.writeln('foo does not exist<br />');
}


if(window.bar) {
  document.writeln('bar exists <br />');
}
else {
  document.writeln('bar does not exist.. not in some places in texas anyway<br />');
}



</script>
</html>

If you add parens like u did it executes. Try without parens.
